Compressive strength refers to the amount of pressure that the material can withstand before it breaks, or, in other words, the maximum crushing stress that a concrete block can take. The ability of a concrete block to endure compression stresses applied to its surface is a highly essential physical attribute of this popular construction material.

compression test-on the other hand, brickwork strength may greatly exceed the cube crushing strength of the mortar used in it. Finally, it has been shown that the compressive strength ofbrickwork varies, roughly, as the square root of the nominal brick crushing strength, and as the third or fourth root of the mortar cube strength.
